first time grower here just wondering if u dont know the strain or anything about trichomes wen do u start to flush? few days after first signs of amber trich's or is there some other indicator wen you should start a 1-2 week flush?
In my opinion, which comes from 3 to 4 years of experience.. the best time to begin flushing out the medium.. is generally in the one to two weeks prior to harvest time.
For example, I personally grow with organics and nothing else. I use organic nutrients, soil, etc.. heck, I'd use organic water if there was such a thing, hehehehe.. but seriously, let me get back on track here. Some growers will tell you that since your using all organics, flushing isn't necessary.. which is all fine and good. However, I'm one of those people that truly believe in the motto 'better safe than sorry' you know.. so even with me using ALL organics.. I still stop feeding my plants 2 weeks prior to my estimated harvesting time.. just to be on the safe side, instead of sorry.
Last thing a grower wants, is to spend 60 to 90 days of their lives giving their plants the utmost love and care.. only to have a totally ruined harvest because the grower didn't take proper precautions to prevent such incidents.
I mean, each to their own.. everyone has their own 'style' of doing things when it comes to growing cannabis. But that's how I personally do things.
So, again... in a nutshell.. the best time to start flushing is generally one to two weeks prior to your estimated harvested time.
Hope that helped you out some..
peace & happy holidays!
